THATCHAM Alarm System (Export Only)

The Thatcham Alarm Module monitors the vehicle doors, liftgate, hood and the interior of the vehicle for unauthorized operation. The vehicle doors, liftgate, and hood use ajar switches as inputs to the BCM to indicate their current status. The interior of the vehicle is secured by the use of Intrusion Sensors. The Intrusion Sensors are used as inputs to the Thatcham Alarm Module to report any motion in the interior of the vehicle. The alarm activates by sounding the siren, flashing the hazard lamps, and the VTSS Indicator Lamp.

Arming

Before arming, all doors, liftgate, and the hood must be completely closed. The system can only be armed by locking the doors with the RKE transmitter.

Disarming

To disarm the alarm system, use the RKE transmitter or turn the ignition on with a valid SKIM key. This will also halt the alarm once it has been activated.

NOTE: A powertrain control module from a vehicle equipped with a vehicle theft security system cannot be used in a vehicle that is not equipped with a vehicle theft security system, if the VTSS indicator lamp comes on after ignition on and stays on, the PCI Bus Communication with the powertrain control module has possibly been lost.
